Evaluation of engine

If you all would, run these engine specs through your engine analyzer programs and post the results. Use as many different programs as you can and include which program in your replies.

350 ci - 4" x 3.5"

5.7" rods

Vortec heads - 1.94 / 1.5, 64cc, 9.1 total cr

Cam - lift: .435" I, .460 E / Duration @.050 212 I / 222 E

1.5 production rockers

Part # 12496820 Dual plane intake

600 cfm vacuum sec. Holley

Stock exhaust manifolds - open

This is a little experiment and I appreciate your help.

I know what it is, I just want to see what everyone comes up with using different programs. I chose it because of its simplicity.

My figures HP and Torque figures are a by product of designing the right cam and consiquently always low. Guess you can't get everything for 20K in programing.

384 Ft Lbs at 3500

321 HP at 5000
Limiting factor is the carburator which for that CI and cam is too small, also can not select open manifolds. Choices are manifolds stock exhaust and HP exhaust W manifolds, or headers W, or W/O mufflers. I selected headers W/mufflers, should be about the same.

With a larger carb(750-780 CFM)

387 Ft Lbs. at 3500

326 HP at 5000
